"Portraits of an Era"

Back in the early 1970s, Polaroid introduced the SX-70, a revolution in photography. Here was the medium at the height of modernity. Into a camera that snapped open and shut, film cartridges were inserted. Then the camera was aimed: point, click, and shoot—and a square-format image came sliding out. The film developed there, right before your eyes. People couldn’t hold back, they started shaking the print to make the image come in faster.
